Abstract According to the question that TB6 titanium alloy parts depending on manual polishing, a polishing method
utilizing the wool wheel is presented. This paper studies the influence of polishing parameters on surface roughness,
surface hardness, and surface residual stress. Polishing parameters are optimized, and this paper has optimized out a set of
polishing parameters: linear velocity vs=19.63m/s, feed speed vf =300mm/min, precompression depth ap=0.5mm, processing
line width w=0.5mm, by which wool wheel polishing can effectively remove the milling pattern, enable the surface roughness
Ra=0.15μm, and ensure that the residual stress of the polished surface is residual compressive stress.
